Purchased two months ago and very happy with performance and amenities. Beautiful addition to the kitchen. Studio series is the way to go and recommend to anyone looking to upgrade their kitchen.

We bought this LG wall oven as part of a remodeled kitchen in our new older home. I was so excited to be able to give her a double wall oven with all the bells and whistles. The most exciting part was having an oven size air fry feature. After using this four or five times with the air fry feature It did not work like an air fry oven. You turn it on you have to wait 15 to 20 minutes before the fan actually starts circulating the air in the oven. Totally defeats the purpose of a quicker cook time. When you air fry it is said that you dont have to defrost items that you place in the oven. You can instantly start cooking because the air circulates but only the LG double wall oven does not. I even had a technician come out and check it out for me. Ive learned thetemperature is set and after a few minutes it reaches its desired temperature. After about 10 minutes the exhaust fan comes on and then 5 minutes later the air fry fan comes on. So youre looking anywhere between 15 and 20 minutes to get to the air fry feature. Dont get me wrong its a beautiful oven but totally disappointed especially at this price

LG Double oven with steam assist

Have had this oven for only one month so we are still exploring its varied functions. Love the style both in and outside and the control panel as well. Made a standing rib roast that was thoroughly enjoyed. Did one steam assist bread that came out nice but need more attempts to be fully satisfied with this function. Only disappointments so far is the soft close doors which fail to close completely on their own. Wonder if I need to call for service b/c of this issue. Lastly but importantly not happy the price dropped several hundred dollars a week or so after we purchased it.

Nine months later.

We waited months for an oven with a steaming feature. It is nothing more than a VERY slow drip on the oven floor. The blue ceramic started coming off after the second auto cleaning. The meat probe was poorly made and came apart simply pulling it out of the socket. Wish I had bought another brand.
